Light carries data through fiber optic cables by sending messages as fast flashes, like when you blink your eyes really quickly to send a secret signal to your friend.
Imagine you and your friend are playing with a flashlight in a dark room. You shine the light on and off, fast, like Morse code! Your friend sees it and knows what message you're sending. That’s how light sends information through fiber optic cables.
How the Light Travels
Fiber optic cables are made of really thin, clear wires, kind of like super skinny straws. When light goes into one end, it zips all the way to the other side, just like a laser beam going down a hallway of mirrors.
These cables are so good at keeping the light on track that they can send messages across cities or even around the world, really fast!
How Data Hides in Light
Data is like a series of quick on and off signals. When you're watching videos or talking to someone online, those actions get turned into these tiny flashes of light.
The more flashes per second, the faster your messages go! It’s like sending a long message with lots of little blinking lights, super fast, and no one needs to whisper secrets anymore.
Examples
